GRAVITY MEASURING-TANK.

SPECIFICATION forming part of Letters Patent No. 546,399, dated September 17, 1895.

Application filed January 24, 1895. Serial No. 536,102. (No model.)

To (ZZZ whom, it may concern:

Be it known that I, JAMES HALL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gravity MeasuringTauks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in measuring-tanks designed for measuring liquids as they are drawn from the tank; and it has for its object, among others, to provide a simple cheap tank having provision for use in connection with a can or receptacle of any height and preferably arranged so that the tank proper shall be concealed from view say in the next or another room. The connection between the tank proper and the measuring vessel is provided with one or more flexible or universal joints, so that the measuring-vessel may be raised orlowered to adapt it for use in connection with a taller or shorter can or receptacle. The 111 easuring-vessel may be provided with an index to indicate the amount drawn therefrom and further provided with an audible alarm to indicate when the said receptacle is filled.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which Figure 1 is a side elevation of my improvement with a portion of the tank broken away and the partition-wall shown in section. V Fig. 2 is an elevation of the device with portions of the tank broken away and the measuringvessel shown in two different positions, one by full and the other by dotted lines. Fig. 3

is an enlarged sectional detail of the upper portion. of the measuringwessel, showing the audible alarm.

Like letters of referenceindicate like parts throughout the several views.

Referring now to the details of the draw ings by letter, A designates atank of any de sired capacity mounted upon a suitable sup port A, and,as seen in Fig. 1, having its bot tom slightly inclined toward the point of conneetion of the discharge-pipe therewith. In Fig. 1 this tank is shown as upon one side of a vertical partition B, through a hole in which passes the pipe 0, which is connected with the lowermost point of the tank A in any suitable manner so as to provide a liquid-tight joint.

D is a measuringwessel of any suitable construction, provided with a tapered outlet-tube E, designed to be placed over or to extend into the neck or opening in the oil-can or other receptacle. It is provided with a cock F, by which the discharge therefrom may be regulatedor entirely shut off. This measuringv'essel is carried by the pipe G, which is connected therewith at a point near the center thereof by any suitable form of k nuckle-joint, the other end of the said pipe being connected with the outer end of the pipe 0 by a suitable movable joint, as shown at g. A cock II is provided in the pipe G, preferably at itsjunction with the measuring-vessel, as shown, so as to control the flow of liquid from the tank into the said vessel. hen the tank and measuring-vessel are located in the same room, of course the pipe 0 is not necessary, and'in this case the pipe G is connected at one end to the measuring-vessel, as before, and its other end is connected by a swivel or union joint, as shown at h in Fig. 2, to the tank or the outlet therefrom. The cock His present in this form and serves the same pnrpose as in the form illustrated in Fig. 1. The measuring-vessel may be provided with an index-glass, as indicated in Fig. 2, so as to mark 013? the quarts, half-gallons, (he, in a manner well known in this class of devices.

With the parts constructed and arranged substantially as hereinbefore set forth the operation will be readily understood, and, briefly stated, is as follows: The cock F is closed and the cook 11 opened, when the oil or other liquid will flow from the tank A through the pipe G or through the pipes Gand Ginto the measuring-vessel 1). When the proper amount has been withdrawn into the measuring-vessel, the cock II is closed and the nippic 13- placed in the neck 1: of the can I, as indicated in Fig. 1, and then the cock F is opened with a tube J, which extends down within the same for a short distance and also above the top thereof. JVithin this tube are placed a short distance apart two diaphragms or disks K, each having a hole 7e therein. This serves a double purpose: first, as a vent to permit of the escape of the air as the vessel is being filled, and, second, as a warning that the measure is full, for while the vessel is being filled the escaping air, passing through the openings in the disks, will produce a whistling noise, which, as the measure becomes full, will cease, the tube projecting sufficiently within the vessel to warn the operator or attendant of the near approach of the liquid to the top of the vessel to permit him to shut off the supply before the vessel is full, and thus prevent running over.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

What I claim as new is 1. The combination of a tank, apipe connected therewith and having a movable or knuckle joint and a measuring vessel carried by said pipe and having a pivotal connection by said tube and diaphragms serve the double function of a vent and an audible alarm, sub stantially as described.

4. The combination of a tank, a pipe connected therewith, a pivoted measuring vessel carried by said pipe with a movable or knuckle joint between the tank and vessel, a cock controlling the supply to said vessel, a discharge nozzle for said vessel, and a cock controlling the discharge therefrom, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
